I am 21 and I found a lump in my breast and got referred to the breast clinic. Once there, they did a mammogram and said I had 2 fibroadenomas. I am currently in a lot of pain surrounding the areas and in my armpit. I've been struggling to put my arm down because of the pain. I would really like to get a second opinion and a biopsy done because I'm still so worried about the amount of pain I'm getting and how uncomfortable I am and worried about what it is.  Has anyone experienced this and was misdiagnosed?? or have you been able to ask for a biopsy and second opinion at the doctors and they have agreed to do it even though you've had a mammogram.
